Force External Storage as Default
I've taken a look through some of the NextCloud docs and found a few things. Does anyone know if you can set external storage as the default storage for all users? I was looking at setting up Backblaze Cloud Storage as a primary for all file storage.
I guess you are looking for https://autoize.com/s3-compatible-storage-for-nextcloud/ ? FWIW, I have tried this some time ago and found the whole thing unstable. It will store these uid objects and not concrete files in the cloud storage which makes me very uneasy. I would only go down this route if you plan to purchase a nextcloud support subscription and they can help you out if things break because it can be impossible to recover data from arbitrary objects.
I also found https://portal.nextcloud.com/article/10/object-store-as-primary-storage-16.html but this seems to be subscriber only, had no idea that nextcloud had such pages.
